Oracle diff:bagaimana cara membandingkan dua tabel?

Coba ini:

(select * from T1 minus select * from T2) -- all rows that are in T1 but not in T2
union all
(select * from T2 minus select * from T1)  -- all rows that are in T2 but not in T1
;

Tidak ada alat eksternal. Tidak ada masalah kinerja dengan union all .
